Oof.

Um, try calming down for a second, and maybe searching the site for specific questions.

You're gonna need to do some serious mods for a 2.4, I think.

Also, try not typing like you just snorted coffee grounds spiked with LSD

 

I don't think you can run a 2.4, if you can it requires grinding the snout.

 

do some researching on the site. then come back to your question and laugh at yourself.
